This is the concept of algebra, given that ab^4=12 and a^5b^5=7776, the value if a will be found as follows: ab^4=12 a=12/b^4 also; a^5=7776/b^5 thus; a=(7776/b^5)^(1/5) a=6/b thus the value of a will be: 6/b=12/b^4 dividing both sides by b we get: 6=12/b^3 multiplying both sides by b^3 we get 6b^3=12 b^3=2 hence; b=2^(1/3)
